  • Distributed storage reservation for recovering distributed data
    Patent number: 10754735
    Abstract: Distributed storage reservation for distributed data recovery is described. A system identifies a total number of connected computers, a storage capacity of each connected computer, and a maximum storage capacity of the identified storage capacities of the connected computers. The system determines a reserved storage capacity based on the maximum storage capacity and a reduced total number of the connected computers. The system provisions the reserved storage capacity in each connected computer. The system stores replicas of a database on the connected computers and on multiple computers, the multiple computers being the same as or different than the connected computers. The system identifies that a connected computer storing a replica of the database is unavailable. The system restores a replica of the database from at least one computer storing one replica to the reserved storage capacity in each of multiple available connected computers.
